Videos should use gpu instead of cpu

[MasoudAjorlou]

Firefox uses too much cpu to show videos and I don't have this problem with google chrome on my old laptop INSPIRON 6400.

@MasoudAjorlou : the graphics-card in your system is from around 2006, so it's not supported.

In Device Manager, on the "Performance" tab, if you don't see "GPU" listed in there it usually means various hardware-acceleration features won't be available, as the drivers are too-old.

Try running YouTube videos at 480p or 720p at most on older devices.

You can install extensions to make YouTube default to a lower quality for each video, like this one:
